Inference Optimization using Relational Algebra

Autor: Evers, S., Fokkinga, M.M., Apers, Peter M.G.

Exact inference procedures in Bayesian networks can be expressed using relational algebra; this provides a common ground for optimizations from the AI and database communities. Specifically, the ability to accomodate sparse representations of probabi

We propose a unified and complete solution for expert finding in organizations, including not only expertise identification, but also expertise selection functionality. The latter two include the use of implicit and explicit preferences of users on m

In situations where disjunct parts of the same process are described by their own first-order Markov models and only one model applies at a time (activity in one model coincides with non-activity in the other models), these models can be joined toget

Possible Histories: A way to model Context-Aware Preferences

Autor: van Bunningen, A.H., Fokkinga, M.M.

Nowadays more and more information becomes available in digital form. To be able to guide users through this wealth of information, a possibility is to only provide the user with relevant information, where relevancy is determined by the preferences

Ignorance in the Relational Model

Autor: Fokkinga, M.M.

Publikováno v: STARTPAGE=33;ENDPAGE=40;TITLE=None

We hypothesize that an extension-with-conditioning of Dempster-Shafer theory is suitable for encoding uncertainty and ignorance in the Relational Model. We present a formal and well-motivated definition of conditioning, and show the spirit of the req
